Wheel hub bearings are used to allow the hub to tum on the axle as well as supporting the weight of the vehicle.They are also referred to as axle bearings.They are used to ensure that the wheels function properly and run smoothly by minimizing friction.The bearing can support both axial and radial loads and are lubricated with heavy and high temperature grease to allow little friction and prevent wear.They also help to keep the rotating wheel attached to the car.
